I have done exactly as you have told. But still i find the error "File Not found" . I have cross checked whether i have put the file in C:\ or not. I have done that.
Can you please help me out.
Thanks in advance

No, you have not done "exactly" as toolic suggested. You're showing us single quotes around the file name. c.f. his line 3 at his first reply. See also any of the standard references re "interpolation."
